The story of a determined Ojibwe Grandmother (Nokomis) Josephine Mandamin and her great love for Nibi (water). Nokomis walks to raise awareness of our need to protect Nibi for future generations, and for all life on the planet. She, along with other women, men, and youth, have walked around all the Great Lakes from the four salt waters, or oceans, to Lake Superior. The walks are full of challenges, and by her example Josephine invites us all to take up our responsibility to protect our water, the giver of life, and to protect our planet for all generations.

The Water Walker is a wonderful book about conservation, environmentalism, and preservation, written in a way that even the youngest audience can understand why Nibi is important and why we should protect Nibi.... The book has the potential to be a highly interactive book around which science lesson plans could be formed. Students can discuss how they are protecting Nibi, they can write letters to Nokomis, and there can be discussion around the ways they can create change in the world, just as Nokomis did.
